Electrochemical Hydrogenation of N‐Heterocycles and Related Substrates: A Mini‐Review

Electrochemical Science Advances, Volume 5, Issue 4, August 2025.
ABSTRACT Catalytic hydrogenation refers to the (often) metal‐mediated addition of dihydrogen (H2) equivalents to unsaturated compounds to form new element‐hydrogen bonds. This conceptually simple reaction is ubiquitous in the production of a vast number of essential chemicals.

Studies on the electrochemical reactions of 1-amino phosphonates

Electrochemistry Communications
Electrochemical direct conversion of 1-aminoalkylphosphonates into novel heteroaromatic compounds has been studied and described. Cyclicvoltametry analysis showed that 1-aminoalkylphosphonate was oxidized in the anode, followed by removing the phosphoryl

Leveraging Tumor Microenvironment to Boost Synergistic Photodynamic Therapy, Ferroptosis Anti‐Tumor Efficiency Based on a Functional Iridium(III) Complex

Advanced Science, Volume 12, Issue 14, April 10, 2025.
Ingenious introduction of an imine bond into an Ir(III)‐ferrocene complex effectively disrupts the photoinduced electron transfer process. Allowing full use of the TME to boost the efficacy of PDT, the molecule releases the Ir(III) complex and ferrocene with synergistic enhanced therapeutic effects of PDT and ferroptosis.

Label‐Free 3D Cell Imaging Using Hydrogels Functionalized with Switchable Iridium Complexes

Chemistry – A European Journal, Volume 31, Issue 19, April 1, 2025.
A label‐free imaging of cells in a 3D scaffold was achieved using switchable Ir‐complexes, covalently linked to a hydrogel. The presence of unstained cells induces the “switch‐on” of the luminescence from the Ir‐complexes, allowing clear visualization of living cells.

Ortho Arylation of N‐Aryl Amides and the Construction of Diagonal Tetraarylbenzenediamines and N‐Doped Fulminenes via BBr3‐Derived Dibromoboracycles

Chemistry – A European Journal, Volume 31, Issue 8, February 6, 2025.
We report the discovery of a boron‐driven ortho‐arylation reaction of N‐aryl amides and ureas. This novel method enables directed borylation of a wide range of substrates, leading to the synthesis of unique compounds such as N‐doped fulminene and diagonal tetraarylbenzenediamines.
